mainlining shenanigans
376bc27150
The current code uses the CLOCKSOURCE_OF_DECLARE macro to fill the clksrc table with a t-uple (name, init_function). Unfortunately it ends up to the clockevent and the clocksource being both initialized with this macro. It is not a problem by itself but there is not a clear distinction between a clockevent and a clocksource in the code initialization path. Somebody can argue there are the same IP block and the same DT node. But conceptually from the software side, there are two distincts entities and as is they should be initialized separetely. Some drivers which do not have a clocksource end up by using the CLOCKSOURCE_OF_DECLARE macro to declare a clockevent. Another result is the fuzzy organization in the clocksource directory, where the clockevents are implemented in the same file than the clocksources or file labelled timer-something implementing a clocksource. This patch provides another macro to specifically declare a clockevent in the same way than the clocksource and gives the opportunity to write two separate drivers, one for the clocksource and another for the clockevents. Hopefully, that can help to do some housework in the directory, perhaps split the drivers in to entities, for example: - clksrc-rockchip.c - clkevt-rockchip.c Also, it gives the possibility to declare clocksources separately in the DT and then use a clocksource from IP block while while clockevents are used from another IP block.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
